LOUIS J. MCGREGOR AND CHARLES M. CARPENTER, OE HYNDMAN, PENNSYLVANIAPAINT-BRUSH.

SPECIFICATION forming part of Letters Patent No. 495,702, dated April18, 1893.

Application tiled December 14, 1392. Serial No. 455|188. (No model.)

To all? whom iz? may concern:

Be it known that we, Louis J. MoGREGoR and CHARLES M. CARPENTER,citizens of the United States, residing at Hyndman, in the county ofBedford and State of Pennsyl- Vania, have invented a new and usefulPaintlrush, of which the following is a specificaion.

Our invention relates to improvements in paint-brushes, and to thatclass thereof in which the bristles are detachably connected with thehandle, whereby new bristles may be added from time to time as theybecome worn and rendered useless, and thus the same handle serves itsuseful purpose for a great length of time, and a saving effected in thecost of the brushes.

The objects and advantages of our invention, together with the novelfeatures. thereof will hereinafter appear and be particularly pointedout in the claims.

Referring to the drawingsz--Figure l is a perspective view of apaint-brush constructed in accordance with our invention. Fig. 2 is anelevation the brush-handle clamping ferrule and tnft of bristles beingdetached and ready to be assembled. Fig. 3 is alongitudinal sectionalview the parts being assembled, or in other words, the brush being readyfor use. Fig. 4 is a transverse section through a tuft of bristles.

Like numerals of reference indicate like parts in all the figures of thedrawings.

l designates a handle of suitable size and length and formed of wood,and the same gradually swells or enlarges toward its lower end, butshort of the same is reduced to form a slightly tapered tenonV 2, abovewhich, by reason of the sudden reduction, is produced an annularshoulder or stop 3.

4 4 designate a pair of semi-tubular clamping jaws, the same beingformed of brass or other metal and of corresponding size and shape.These clamping jaws are of such combined diameter as when placedtogether to form a tube or ferrule they will be slightly less than thegreatest diameter of the tenon 2. The clamping-jaws 4-4 are provided attheir rear ends with semicircular ribs or bosses 5, and in advance ofsaid bosses, but in rear of their centers they are slightly skived outor reduced as at G. Mounted upon the ferrule thus produced by theaforesaid assemblage of the jaws is a sliding ring 7, said ring havingan interior diameter equal to the combined external diameter of the jawsin front of or below that point thereof at which they are skived orreduced, and hence said ring has an internal diameter slightly exceedingthe external diameter of the two jaws when they are assembled and atthat point thereof that is skived or reduced. At the same time theshoulder or boss at the rear end of the ferrule serves as a limitingdevice for preventing a withdrawal of the ring in an upward or rearwarddirection.

S designates a tuft of bristles that are put together without glue andwith the simple wrapping or binding-cord 9. In the present instance thebristles form a cylindrical tuft, in that the brush to be produced iscylindrical, but it will be understood that the bristles may be boundupon a filling plug as indicated in section in Fig. 4, when an oblongbrush is required. In such instance, also, the handle and the ferrulewould likewise be altered in shape, the principle and features ofconstruction remaining the same.

To assemble the parts and produce the brush, the sliding ring is movedto the rear or upper end of the ferrule until its movement is arrestedby contacting with the annular enlargement or boss at the upper rear endof the ferrule. This will permit, by reason of the loose fitting of thering upon the ferrule at this point, of a spread of the two jaws attheir front ends, and when this has been accomplished the butt-end ofthe tuft of the bristles is inserted into said ferrule at its spreadend. The ring is now pushed down about the .center of the ferrule thusclamping the two jaws upon the bristles, after which the tapered tenonof the handle is forced into the upper or rear end of the ferrule, thusslightly spreading to a very limited degree the upper or rear ends ofthe jaws, and still further clamping the front ends ofthe jaws upon thebristles. It will be seen that the ring remaining in the middle or nearthat point, serves as a fulcrum, and while the tuft of bristles clampthe upper or rear ends ICO of the jaws upon the handle the tapered endof the handle serves also to spread said upper or rear end and clamp thejaws upon the bristles. As a result an exceedingly secure and eiiicientconnection is formed between the bristles and the handle, in which weavoid all use of glue and other expensive constructions. To remove thebristles when they are worn it is simply necessary to withdraw thehandle, which permits the upper or rear ends of the jaws to cometogether, and hence loosens the ring so that it maybe readily slid tothe upper or rear end of the ferrule, which loosens the front ends ofthe jaws and permits of a ready withdrawal of the bristles from theferrule.

Having described our invention, whatwe claim isl. The combination with ahandle, and a tuft of bristles, of a connecting device consisting of apair of transversely curved independent jaws adapted to clamp the tuttof bristles, and at their opposite ends a handle, and a sliding ringmounted on the jaws and adapted to bind the same in position upon thehandle and bristles, substantially as specified. Y

2. The combination with a handle reduced at one end to form a taperedtenen, and a tuf t ot bristles, of an intermediate connecting deviceconsistingr of a pair of semi-cylindrical jaws enlarged externally attheir rear ends and in advance of such enlarged portions slightlyreduced externally, said jaws being of a combined internal diameteragreeing with the smallest portion of the tapered tenon, and a slidingring mounted on the jaws and having an internal diameter agreeing withthe greatest external diameter of said jaws with the exception of theenlargement at the rear end thereof, substantially as specified.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
